Abstract (en)
[origin: EP4095937A1] A display substrate, comprising a plurality of sub-pixels (SP) arranged in a plurality of rows and columns, and comprising a base substrate (101), a driving circuit layer (102), a light-emitting device layer and a black matrix layer (113), wherein each sub-pixel (SP) comprises a pixel driving circuit provided in the driving circuit layer (102) and a light-emitting device (EM) provided in the light-emitting device layer, the pixel driving circuit is configured to drive the light-emitting device (EM), the driving circuit layer (102) comprises first signal lines (S1) and second signal lines (S2) which are provided in parallel and arranged periodically, the first signal lines (S1) and the second signal lines (S2) are configured to provide different electrical signals to the plurality of sub-pixels (SP), the black matrix layer (113) comprises a plurality of first light-transmitting openings (1131) and a plurality of second light-transmitting openings (1132), the plurality of first light-transmitting openings (1131) respectively expose the light-emitting devices (EM) of the plurality of sub-pixels (SP), the plurality of second light-transmitting openings (1132) are respectively provided between the plurality of first light-transmitting openings (1131), and the orthogonal projections of the plurality of second light-transmitting openings (1132) on the base substrate (101) are each located between the orthographic projection of a first signal line (S1) on the base substrate (101) and the orthographic projection of a second signal line (S2) closest to the first signal line (S1) on the base substrate (101). A display device, comprising the display substrate. The display substrate realizes light transmission at the plurality of second light-transmitting openings, thereby facilitating the realization of functions such as fingerprint recognition.
